I'm trying to run the example simple_cbr, but I'm getting this error:

.....jbossesb/samples/quickstarts/simple_cbr/build.xml:15: java.lang.OutOfMemoryError: unable to create new native thread

Total time: 1 minute 4 seconds
java.lang.OutOfMemoryError: unable to create new native thread


How much memory is needed ? I have 1GB.


I already stripped down JBossAS and JBoss ESB to a minimal configuration without all the HTTP stuff:

1. contract.war
2. http-invoker.sar
3. jboss-web.deployer
4. jbossws.sar
5. jbpm.esb/jbpm-console.war
6. jms/jbossmq-httpil.sar
7. jmx-console.war
8. management/console-mgr.sar
9. soap.esb
10. soapui-client.sar

Now it works... but after a few times, I'm getting the error again. And all the system fails with:

/usr/bin/lesspipe: fork: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable


Thanks in advance,
Eric
